Ulf:
First, welcome!
Nice to have you aboard.
I am one of the progarchives official "collaborators." And although, of course, anyone and everyone can listen to and review Italian prog, it happens to be one of the two areas in which I have the greatest interest, and in which I am most active in my reviewing.
I have been listening a great deal of Italian prog lately, and agree with you that Italy is producing, overall, perhaps the best new prog of any country (including England, a close second). That said, not all Italian prog bands are as "successful" (musically) as others; some have better musicians, some have better writing, etc.
A few you might check out (if you have not done so already) are (in alphabetical order): Banco del Mutuo Soccorso, Consorzio Acqua Potabile, Deus ex Machina, Il Balletto di Bronzo, and Museo Rosenbach. (You can check out my reviews of some of these groups' albums by clicking on the "collaborators" button on the top of the home page, then clicking on my name - Ian Alterman - on the right side).
For my money, Deus ex Machina is not only producing the best Italian prog right now, but some of the best prog anywhere. I have heard three of their six albums (two more reviews are forthcoming), and am absolutely blown away by everything they do. (In this regard, read my review of "Equilibrismo di Sofferenza.") I also really like Museo Rosenbach (an older group) and, to a slightly lesser extent, Banco del Mutuo Soccorso. I was less impressed by (but still found very interesting) Il Balletto di Bronzo and Consorzio Acqua Potabile.
I am always open to any Italian prog, so if you have suggestions, by all means share them.
In the meantime, welcome to the site!!
Peace.
